Except that I already have an unlimited data connection with a hotspot... in my iPhone. My question is, why don't car manufacturers reverse their paradigm, and just piggyback off of existing connections for all of the embedded head units data requirements?* When I'm out and about, my iPhone is with me. When I'm at home, my WiFi is available. I always have some form of data connectivity available, already... there's absolutely no value (to me) to putting yet another data connection in my car.**
* Don't bother answering... it's rhetorical. We all know perfectly well that the only reason they don't support my suggested use case is that they wouldn't be able to charge for a data connection.
** Until real self-driving comes on the scene, allowing me to tell my car to come pick me up. That's the only legitimate use case... and it's still years off.
